Question: How can I define a linear transformation?

Dear All,

I want to define a linear transformation called T, an operator on the variable x. This transformation is such that, for example, the transformation T(alpha__1*x^2*y+alpha__2*x^4*t+alpha__3*t*y) returns alpha__1*y*T(x^2)+alpha__2*t*T(x^4)+alpha__3*t*y*T(1).

Can anyone help me in this matter? At this stage of the work, I don't have a precise definition of this linear transformation.

T(alpha__1*x^2*y+alpha__2*x^4*t+alpha__3*t*y)=alpha__1*y*T(x^2)+alpha__2*t*T(x^4)+alpha__3*t*y*T(1);

Best wishes
